How to prove Jesus is the Messiah using the Tanakh (Old Testament) only

Is Yeshua (Jesus) identified in the Old Testament?

Judaism teaches the death of the righteous brings atonement to the world. According to the Zohar: "As long as Israel dwelt in the Holy Land, the rituals and the sacrifices they performed [in the Temple] removed all those diseases from the world; now the Messiah removes them form the children of the world (2:212a). "Rabbi Hiyya Bar Abba said: "The sons Aaron [Nadab and Abihu] died the first day of Nisan.  Why then does the Torah mention their death in conjunction with the Day of Atonement? . . . it is to teach that just as the Day of Atonement atones, so also the death of the righteous atones." (Leviticus Rabbah 20:12)

Scriptures from Tanakh (the Old Testament) that reveal the death of the righteous atones:

2 Samuel 21:1-14; Numbers 8:19; Deut 24:16 (AJOJ - MB p. 295); 25:1-13; Numbers 35:25-28; Isaiah 53:4-6, 12

• ‘On this day (i.e., Yom Kippur, Leviticus 16:30) on the mountain of the Lord, Isaac’s ashes shall be seen, heaped up and standing for atonement (Rashi, on Genesis 22:14)
• The Rabbis said:  His name (Messiah’s name based on the context-emphasis mine) is the leper scholar as it is written, Surely he has borne our griefs and carried our sorrows: yet we did esteem him a leper, smitten of God and afflicted (b. Sandhedrin 98b - refer to Isaiah 53:4 as talking about the Messiah)

Scriptures from the Tanakh that prove the divinity of the Messiah:

Genesis 3:15, 22; Genesis 11:6-7; Joshua 5:13-15; Exodus 3:2-6; Deuteronomy 6:4; Isaiah 7:14; 9:6; 11:1-3; 44:6; 48:16-17; Psalm 45:1-7; 110:1-4; Daniel 7:13-22; Proverbs 30:4; Zechariah 14:1-4

The Hebrew word used for "one" in Deuteronomy 6:4 is echad which means a composite unity. Rambam used yachid or yahid which means only one.
